5. Copernicus -Poland (early 16th c.)  Contributions in Astronomy, Physics and Math  Geocentric Theory was inaccurate/believed in heliocentric theory  Developed Mathematical Explanations  Created a Complete Model of the Solar System  Revolutions of the Heavenly Spheres

6. Kepler  Found that the planets orbited in an oval pattern (study of celestial mechanics)  Used Mathematical Theory to develop a model of the solar system  Founder of modern science of astronomy  Wanted to Prove Copernicus Wrong but Instead Proved the Heliocentric Theory Correct  “Theory must fit the facts”

7. Galileo -Italy (early 17th c.)  Built first telescope strengthening heliocentric theory  Claimed that the Bible should not be used to prove scientific theory  Accused of heresy because beliefs questioned the Bible and undermined Christian thought

8. Newton -England (late 17th c.)  Brought together Astronomy, Physics and Math  Demonstrated that mathematics (calculus) could be used to explain the effects of gravity  Devised three theories of motion, forming his theory of gravity from these laws  Principia

9.  The Age of Reason - 1600’s & 1700’s Philosophes viewed reason as the best way to understand the truth Philosophes viewed reason as the best way to understand the truth New ideas were debated and writings were published questioning ideas long held as absolute truth New ideas were debated and writings were published questioning ideas long held as absolute truth Natural law or a universal moral law (truth) could be understood by applying reason Natural law or a universal moral law (truth) could be understood by applying reason Challenged beliefs in absolute monarchies Challenged beliefs in absolute monarchies Questioned relationship between church and state Questioned relationship between church and state Debated rules and rights of people in society Debated rules and rights of people in society Believed in the freedom of speech and individual liberties Believed in the freedom of speech and individual liberties

10. Political Philosophy  Thomas Hobbes  John Locke  Jean-Jacques Rousseau  Baron de Montesquieu  Adam Smith

14. Montesquieu -France (18th c.)  Believed that a separation of power would keep people from abusing power  A system of checks and balances would prevent the rise of despotism  The Spirit of the Laws Legislative, executive, judicial Legislative, executive, judicial

15. Adam Smith  “Father of Economics”  Supported Laissez- Faire economics Govn’t should have a hands off approach in business Competition would lead to the appropriate pricing of goods Supply and demand help determine the prices of goods
